Weegy: Life-cycle assessment (LCA, also known as life-cycle analysis, ecobalance, and cradle-to-grave analysis)[1] is a technique to assess environmental impacts associated with all the stages of a product's life from-cradle-to-grave (i.e., [ from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling). LCAs can help avoid a narrow outlook on environmental concerns by:
Compiling an inventory of relevant energy and material inputs and environmental releases;
Evaluating the potential impacts associated with identified inputs and releases;
Interpreting the results to help make a more informed decision.
The goal of LCA is to compare the full range of environmental effects assignable to products and services in order to improve processes, support policy and provide a sound basis for informed decisions.[3]
The term life cycle refers to the notion that a fair, holistic assessment requires the assessment of raw-material production, manufacture, distribution, use and disposal including all intervening transportation steps necessary or caused by the product's existence.

Weegy: To describe what risk communication is, it is helpful to begin with what it is not. [ Risk communication began in the late 1970s with efforts by the nuclear and chemical industries in the United States to counteract widespread public concern about those technologies. It was believed that clear, understandable information was all that was needed to make people see that the risks were lower than many feared. To this day, many still believe risk communication is just a matter of making information understandable. This is particularly true in fields like nuclear technology, strongly influenced by people with scientific and engineering backgrounds.
For decades this approach has failed, and most risk communication experts say it is inadequate. The perception of risk, and the behaviors that result, are a matter of both the facts and our feelings and instincts and personal life circumstances. Communication that offers the facts but fails to account for the affective side of our risk perceptions is simply incomplete.
Risk communication is also commonly thought of as what to say under crisis circumstances. This too is inadequate. While it is certainly true that communication in times of crises is important in managing public response, countless examples have taught that a great deal of the effectiveness of risk communication during a crisis is based on what was done beforehand.
